The singer, who is married to Josh Duhamel, requested the change last month. According to the documents she filed in L.A. County Superior Court, she wanted to "conform to the first name which she is commonly and professionally known as, and has been for many years."

Before receiving approval, she was required to publish a notice in a local newspaper for four weeks. It's the same process that Ron Artest, who currently plays for the New York Knicks, went through before becoming Metta World Peace two years ago.
